' Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed Aprili7,'1908. Serial No. 425,695.

To all 'whom it may concern:

Be it known that I, lzlm B. ZooK, a citizen of the United States, residing at Leola, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Gearing, of which the following is a specification, reference heng had therein to the accompanying drawing.

My invention relates to an improved pumping-jack or convertible hand or poweroperated power-head for vdeep-well pumps, or other mechanical operation requiring a movement of like nature.

'lhe objects of my invention are to produce a simple, durable and ellicient device, and also to provide a novel means whereby the jack cannot be operated by power when the' hand-lever is attached, thus eliminating all danger of accident caused` by applying the power while the hand-lever is in use; and further by the mode of gearing which I eniploy, I impart a great etliciency of operation with a small amount of power applied.

.To this end my invention consists in certain features of construction and combination of parts, which are fully described and f claimed in the annexed speclcatlon, and 1t is fully understood that I do not confine myself to the exact design as shown, as slight changes may be made in the construction without departing from the spirit of the invention.D

Like reference numbers indicate corresponding parts in all the figures of the drawings.

In the drawings -Figure 1, is a perspeo tive View of the jack in position, showin@ the rear. Fig. :2, 1s a perspective view of the j jack in position, showing the front. Fig. 3,

V cured therein by the action. of the bell-crank catch Q0, which 1s puuoned between the ears is an elevation of the spur gear, and lever case, showing the hand-lever attached and power detached. Fig. 4, is a sectional View of Fig. 3, on the linea: az. Fig. 5, is an elevation of the spur gear, and lever-case, showing the hand-lever detached and removed and the lever-case attached to the v spur gear to operate the jack by power. Fig.

6, is a sectional View of Fig. 5, on the -line Z/w'y- In said drawings, 1, indicates the mam frame, which is provided with the bands 2,

which embrace and are secured to the suction or Well pipe 3. To the upper end of said frame 1, and integral therewith is formed the horizontal bearing 4, from the l i l forward end of which radiate the arms 5, t the outer ends of which is secured the intel'- nal gear (S, and which isfurther braced and secured to said frame near its lower edge in any suitable manner and here shown as integral therewith. At the side of said frame 1, on a line with the upper band 2, and ex-' tending rearwardly at right angles thereto, and parallel with the bearing d, and integral with said frame, is the bearing sleeve T.

In the main bearing 4, is journaled the shaft 8, to the forward end of which is rigidly secured the. crank arm, and near the rear .end of which is rotatably secured the spur gear 10, while upon the outer end of said crank arm 9, is rotatably mounted the pinion 1l, which meshes with and revolves within the internal gear G. To the outer side of said pinion, near its periphery, is secured a wrist. pin 12, upon which is rotatably mounted the end of the suction rod 13, and b v the arrangement of said pinion and crank, said rod 13, will have a vertical movement imparted to it as the pinion 11, isj rotated within said internal gear G.

The spur gear 10, meshes with and is rotated by al pinion 1l, which is rigidly secured to the rear end of a counter-shaft 15,

journaled within the bearing sleeve 7, while to the forward end of said counter-shaft 15, is rigidly secured the power pully 16, for the purpose of transmitting power to said train of gears.

To the rear end of the shaft S. is rigidly Secured the handle casing 17, at right angles to said shaft and which is formed at one end with the orifice to receive the end of said shaft, and on itsside with the hand-lever socket 1S, adapted to receive the squared end of the hand-lever 19, which is detachably se- 21, of said socket 19, and while in the position shown in Fig. 8, has its end in engagement with a transverse groove 22, provided in the surface of said hand-lever, thus securely retaining said hand-lever within said socket. In the bottom of said socket 18,and extending therethrough is the orifice 23, placed in such a position that the arm 24, of the `bell-crank 20, will enter it and extend therethrough when the hand-lever 19, is removed and the bell-crank 20, placed in position as shown in Fig. 5, and into engagement with the slot 26, in the spoke of the gear which will lock said case and gear together.

p the belt power. 1

'lln` other arm of said crank is irovided! with the finger grip 25; By this novel method it will be readily seen that when the hand-lever is attached and operated, the lever-case 17, being attached to the shaft 8, in proper relation to the wrist pin 12, the suction rod 13, will be operated in the usual way, and the gear wheel 10, which is connected to the power pulley by the pinion 14, and counter-shaft 15, will be at rest, while if the hand-lever 19, is removed and the lever-casing 17, secured to the gear 10, by the bell-crank catch 20, the power will be communicated to the suction rod by said train of gears.

The operation of the device will be' so readily understood that it will only be necessary to further say that when the hand-lever is removed by releasing the bell-crank catch, and the bell-crank catch turned to bring the engaging lug into engagement withthe slot in the spoke of the spur-gear through the registering slot in the lever-case, vthis action will lock said spur-gear to said lever-case, thus connecting the main shaft to the counter-shaft for operating the mechanism by 'Having thus described my invention what l claim as new and desire to secure by Letters Patent is v 1.,l ln a gearing of the class described, comprising a gear supporting frame adapted to Abe attached to the pump standard, and formed with parallel horizontal vshaft bearings, an internal gear ,secured to said frame near its upper end, ,by arms radiating from the upper shaft'` bearing, integral therewith and with said internal gear near the periphery thereof, ay main shaft journaled in said upper bearing, a crank-arm secured upon one end osaid shaft and provided with a wrist-pin, a pinion rotatably mounted upon said wristpin and adapted to m'esh with and rotate within said internal gear, a suction rod head rotatably mounted upon said wrist-pin, and adapted to be raised and lowered by the rotation of said pinion.

2. In a gearing of the class described, a

gear supporting frame, amain shaft and a cured to said counter-shaft journaled in horizontal bearings secured in parallel relation to each soar-fia other and integral with said gear frame, an internal gear concentrlc wlth said main shaft bearlng and Secured to said frame, a
